dc.description.abstractenDue the increasing demand for food worldwide and overexploitation, nontraditional fishery resources have been proposed as an alternative to those offered by existing fisheries. In this regard, some fisheries are considering exploiting bottom fish species with high potential economic value. Therefore, in this study the community structure of resources on the west coast of Peninsula of Baja California was studied to establish basic population parameters of the most abundant species. Two surveys were carried out to evaluate the community structure, the first one was throughout November 2006 and the second one was in March 2007. The most abundant species found were: Bellator gymnostethus, Citharichthys xanthostigma, Hippoglossina stomata, Katetostoma averruncus, Merluccius angustimanus, Porichthys analis, Prionotus albirostris, P. stephanophrys y Synodus lucioceps. Significant differences between total and evenness of the numbers of individuals were observed into two samplings, but not in diversity and species richness. The fish community consisted mainly of widely distributed species of the Tropical Eastern Pacific. It was found that H. stomata, P. albirostris and S. lucioceps were collected at greater depths than previously reported; also a more northerly distribution of B. gymnostethus, P. analis and P. albirostris was observed, probably due to an increase of the sea surface temperature throughout 2006. Of 110 species found, 44 had national commercial importance and 4 international, of the later, two have fishery potential.es_MX
